crosstalk

 [kros´tawk]
in cardiology, inappropriate detection of the atrial stimulus by the ventricular sensing mechanism, usually seen with dual chamber pacemakers; it can lead to asystole. Pacemakers are now able to respond to crosstalk with an obligatory ventricular pacing stimulus at a shorter than average A-V interval.

crosstalk

An artefact in MRI images caused by interference between adjacent slices of a scan, which can be reduced or eliminated by limiting the minimum spacing between slices.
